Patagonia Men's Nano-Air Light Vest

Breathable Fabric with Stretch

Shell and lining fabric built from 100% recycled polyester ripstop is stretchy, breathable, abrasion resistant and comfortable next to skin, with a durable water repellent (DWR) finish made without intentionally added PFAS to resist light moisture

Revolutionary Insulation

40-g FullRange® insulation is warm, stretchy and exceptionally air permeable; combined with the shell and lining, this provides excellent mobility and breathability

Designed for Freedom of Movement

Vest pattern offers total range of motion around arms and shoulders; strategically placed, low-profile quilting combined with stretchy fabric and insulation provides easy layering and unhindered mobility

Center-Front Zipper

Center-front zipper has a zipper garage at the chin for next-to-skin comfort

Pocket Features

Two zippered handwarmer pockets and a zippered left-chest pocket are low profile and low bulk to wear comfortably with a harness or pack; the vest self-stuffs into the chest pocket

Low-Bulk Design

Cleanly finished armholes and hem are low bulk and keep things simple
